Honda Car Forum

Hi all, I have a 93 civic cx hatch, 180000km, but evertime the car
decelerate from a speed above 40-60km/h, it will always jerk between the
switch of gears from lets say 3ird to 2nd at about 30km/h. As if a guy was
downshifting a manual tranny very harshly. There is no way to eliminate the
problem while driving meaning that even if I decelerate very very slowly or
almost slam the brakes, once it's at about 30km/h it will always jerk. there
is not distinct sounds, no metal sounds whatsoever, just the engine reving
faster.

Also, if going lets say about 60km/h, than put car in neutral, wait a second
or 2, and re-engage into the Drive position, it will jerk and put itself
into 3ird and then into 4th which is overdrive i think. So why not go into
4th so that it's smoother, than downsift into 3ird should more power be
needed.
All cars I know will always keep the higher gear unless power is needed. So
this happens at every stop, highway exits.... not so bad in summer but this
winter, it almost blocked the wheels on very slippery roads.

I tried al sorts of tranny oil additives. no change.
Did a full tranny fluid + filter change, still no change.
could it be a solenoid or something. I was told by a honda dealer in the
area that i was better off to just leave it like that, not to spend any $$$
on it and basically let it live what it has left. (not too encouraging)
Speeding up across the gears is all fine, yet the switching could be a bit
smoother but still, I don't even notice.

any ideas????

you did a filter change? unlikely - it's not accessible without
stripping the transmission down.

yes, i have an idea. drain the aftermarket fluids you've got in there &
use honda transmission fluid. it really is smoother. you'll need to do
it 2 or 3 times over a period of a couple of weeks each time, but it'll
smooth it out, not totally, but well enough. honda fluid's cheaper if
you order it online at manchesterhonda.com.
